Fingerprint capture system, fingerprint capture device, image processing apparatus, fingerprint capture method, and storage medium

Abstract

A fingerprint capture system, a fingerprint capture device, an image processing apparatus, a fingerprint capture method, and a storage medium that can acquire a high quality fingerprint image are provided. A disclosed example includes: a capture unit that captures a fingerprint; an image processing unit that processes a transferred fingerprint image captured by the capture unit; a display unit on which the fingerprint image transferred to the image processing unit is displayed; a recording unit where the fingerprint image transferred to the image processing unit is recorded by the image processing unit; and an instruction unit that inputs, in the image processing unit, a record instruction that instructs the image processing unit to record the fingerprint image in the recording unit. The image processing unit records, in the recording unit, the fingerprint image displayed on the display unit at the time the record instruction is input by the instruction unit.

The invention claimed is: 
     
       1. A fingerprint image processing device comprising:
 a memory; and 
 a processor coupled to the memory and configured to: 
 receive a plurality of fingerprint images of a same fingerprint which are sequentially captured and sequentially transmitted by an imaging sensor; 
 store the received plurality of fingerprint images into a temporary storage; 
 display at least one of the plurality of fingerprint images sequentially one by one on a fingerprint display region in a screen of a display unit; 
 receive an input of a record instruction which instructs to record a fingerprint image in a non-transitory storage; and 
 when the input of the record instruction is received, execute:
 specifying, as a designated fingerprint image, a fingerprint image that is displayed on the fingerprint display region at a timing when the input of the record instruction is received; 
 determining whether or not quality of the designated fingerprint image is better than a predetermined criterion of quality; and 
 displaying, when the quality of the designated fingerprint image is not better than the predetermined criterion, information indicating that the quality of the designated fingerprint image is not better than the predetermined criterion to urge an operator who input the record instruction to the fingerprint image processing device to input the record instruction again. 
 
 
     
     
       2. The fingerprint image processing device according to  claim 1 , wherein the processor is configured to
 display each fingerprint image of the at least one of the plurality of fingerprint images on the fingerprint display region for time period enough for the operator to review the displayed fingerprint image to determine whether or not quality of the displayed fingerprint image is acceptable. 
 
     
     
       3. The fingerprint image processing device according to  claim 1 , wherein the processor is configured to
 display each fingerprint image of the at least one of the plurality of fingerprint images on the fingerprint display region for at least 0.6 seconds. 
 
     
     
       4. A fingerprint image processing device comprising:
 receiving a plurality of fingerprint images of a same fingerprint which are sequentially captured and sequentially transmitted by an imaging sensor; 
 storing the received plurality of fingerprint images into a temporary storage; 
 displaying at least one of the plurality of fingerprint images sequentially one by one on a fingerprint display region in a screen of a display unit; 
 receiving an input of a record instruction which instructs to record a fingerprint image in a non-transitory storage; and 
 when the input of the record instruction is received, executing:
 specifying, as a designated fingerprint image, a fingerprint image that is displayed on the fingerprint display region at a timing when the input of the record instruction is received; 
 determining whether or not quality of the designated fingerprint image is better than a predetermined criterion of quality; and 
 displaying, when the quality of the designated fingerprint image is not better than the predetermined criterion, information indicating that the quality of the designated fingerprint image is not better than the predetermined criterion to urge an operator who input the record instruction to the fingerprint image processing device to input the record instruction again. 
 
 
     
     
       5. The fingerprint image processing device according to  claim 4 , comprising
 displaying each fingerprint image of the at least one of the plurality of fingerprint images on the fingerprint display region for time period enough for the operator to review the displayed fingerprint image to determine whether or not quality of the displayed fingerprint image is acceptable. 
 
     
     
       6. The fingerprint image processing device according to  claim 4 , comprising
 displaying each fingerprint image of the at least one of the plurality of fingerprint images on the fingerprint display region for at least 0.6 seconds. 
 
     
     
       7. A non-transitory computer-readable storage medium storing a program that causes a computer to perform:
 receiving a plurality of fingerprint images of a same fingerprint which are sequentially captured and sequentially transmitted by an imaging sensor; 
 storing the received plurality of fingerprint images into a temporary storage; 
 displaying at least one of the plurality of fingerprint images sequentially one by one on a fingerprint display region in a screen of a display unit; 
 receiving an input of a record instruction which instructs to record a fingerprint image in a non-transitory storage; and 
 when the input of the record instruction is received, executing:
 specifying, as a designated fingerprint image, a fingerprint image that is displayed on the fingerprint display region at a timing when the input of the record instruction is received; 
 determining whether or not quality of the designated fingerprint image is better than a predetermined criterion of quality; and 
 displaying, when the quality of the designated fingerprint image is not better than the predetermined criterion, information indicating that the quality of the designated fingerprint image is not better than the predetermined criterion to urge an operator who input the record instruction to the fingerprint image processing device to input the record instruction again. 
 
 
     
     
       8. The storage medium according to  claim 7 , wherein the program causes the computer to perform
 displaying each fingerprint image of the at least one of the plurality of fingerprint images on the fingerprint display region for time period enough for the operator to review the displayed fingerprint image to determine whether or not quality of the displayed fingerprint image is acceptable. 
 
     
     
       9. The storage medium according to  claim 7 , wherein the program causes the computer to perform
 displaying each fingerprint image of the at least one of the plurality of fingerprint images on the fingerprint display region for at least 0.6 seconds.
